Manhunters: before of Green Lantern Corps creation the Guardians of the Universe created the Manhunters to bring peace in the universe. However, the Manhunters became obsessed with the act of 'hunting' criminals. Their code, "No Man Escapes The Manhunters", became more important to them than seeing justice done.

Red Lantern Corps:The Red Lantern Corps were formed by Atrocitus of the Five Inversions, one of the five survivors of the Massacre of Sector 666.

The Red Lantern Ring was born out of anger and crystalized the blood of the Inversions.

This is where their Central Power Battery is to be found, and which is fueled by the remains of the Anti-Monitor (Antimatter Universe).

Infected with evil and overwhelmed by Nekron's influence, she has worked to destabilize the Green Lantern Corps from within and to limit their effectiveness in fighting the Blackest Night.
